Electromagnetic interference can be a serious problem for electronic devices, so shielding is usually placed around components. Now, engineers at Drexel University have found that a 2D material called titanium carbonitride is an excellent shielding mat… Continue reading 2D material absorbs electromagnetic waves for superior shielding
Containing the electromagnetic radiation generated by electronic components is a key consideration for designers of electronic devices, but today’s metal-based shielding materials have their downsides. Scientists at the Swiss Federal Laboratories for M… Continue reading Aerogel fashioned into world’s lightest electromagnetic shielding
We humans may not have superpowers, but the sensor suite we have is still pretty impressive. We have binocular vision that autofocuses and can detect a single photon, skin studded with sensors for touch, heat, and pain, and a sense of smell that can detect chemicals down to the parts …read more

The Israeli health ministry released a smartphone app which takes location data from users’ phones in an attempt to determine if they might have been exposed to the COVID-19 Coronavirus.
Should you be worried about your privacy? Perhaps not.

Microcontrollers tend to consume other kinds of electronics. A project you might once have done with a 555 now probably has a cheap microcontroller in it. Music synthesizers? RC controllers? Most likely, all microcontroller-based now. We always thought RF electronics would be immune to that, but the last decade or …read more

For Game of Thrones fans, it’s an awkward time. The show has ended its run on HBO (not without a certain level of controversy), the planned prequel is still years away, and who knows when George R. R. Martin will actually get around to writing the final books in the …read more

For smaller microcontrollers, having enough outputs for the job is sometimes a challenge. A common solution is to do some sort of multiplexing with the available outputs or perhaps something more advanced such as Charlieplexing, but another good option is to use a specialized driver board. What’s even better is …read more
The Adafruit Feather is the latest platform for microcontroller development, and companies like Particle, Sparkfun, Seeed Studios, and of course Adafruit are producing Feather-compatible devices for development and prototyping. Now it’s your turn! The Take Flight With Feather contest challenges you to design a board to fit in the Feather …read more

For serious data collection with weather sensors, a solar shield is crucial. The shield protects temperature and humidity sensors from direct sunlight, as well as rain and other inclement weather, without interfering with their operation. [Mare] managed to create an economical and effective shield for under three euros in materials. …read more

The New York State Legislature recently passed a bill that aims to protect New York residents, regardless of the location of the business. The law, known as the Stop Hacks and Improve Electronic Data Security (SHIELD) Act is designed to address unautho… Continue reading New York Passes a Law that Further Expands Cyber Protection
